My experiment

The aim of my investigation is to observe what happens when an acid reacts with another material.

The hypothesis of my research is that I think the egg he break the shell. 

First I put one egg on the vinegar.

The first day the egg change a litle, he got a special red liquid and the egg cover with bubbles.

The second day the egg was exactly the same.
The third day the egg begins to change the sell start to take off.

The last day the egg not have the sell.
